Button Head Tool for #8 Screws
Looks like a rivet! The most unique idea we know of for tamper-proof fasteners.... the Button Head, once installed, looks more like a rivet than a screw. Slightly out of round, the Button Head can be installed and removed only with a special tool. The head is case hardened and tapered, to resist the grip if pliers or vise grips. 100 piece packs.
